Sila[1]ruthenocenophanes: Long Sought‐After Family Members
Bibliographic record
Abstract
During the last three decades, silicon-bridged [1]ferrocenophanes have been developed into an important class of monomers with the resulting polymers being the subject of hundreds of publications. For unknown reasons, not a single example of a silicon-bridged [1]ruthenocenophane is described in the literature. We set out to address this mystery and could synthesize the first sila[1]ruthenocenophanes. Their molecular structures as well as their heat release in the melt, render them as highly strained sandwich compounds that are polymerizable. Why did it take so long to prepare the first sila[1]ruthenocenophanes? This question is addressed by a detailed analysis of the kinetics of the salt-metathesis approach, which reveals a striking difference between ferrocene and ruthenocene.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
